Like I said, it is something that should be pull requested to the upstream, and if that fails, then fork. The fork is a secondary path to cooperation.

If the conclusions are that the platform cannot support cursor acceleration the proper way (i.e. the way all commercial OSes do), the premise of the library is flawed. If not, then it must be the whole OS that's flawed, because that needs to be possible on a desktop system. Linux's cursor acceleration sucks, there is no excuse for the whole UI layer of the ecosystem being as bad as it is.
